Message-ID: <20110324185258.GA28370@elte.hu> (raw)
In-Reply-To: <20110324172653.GA28507@elte.hu>
There's a different crash triggered by the slub merge as well, i've bisected it
back to one of these commits:
09b9cc4: sd: Fail discard requests when logical block provisioning has been disabled
a24c5a0: slub: Dont define useless label in the !CONFIG_CMPXCHG_LOCAL case
5bfe53a: slab,rcu: don't assume the size of struct rcu_head
da9a638: slub,rcu: don't assume the size of struct rcu_head
ab9a0f1: slub: automatically reserve bytes at the end of slab
8a5ec0b: Lockless (and preemptless) fastpaths for slub
d3f661d: slub: Get rid of slab_free_hook_irq()
1a757fe: slub: min_partial needs to be in first cacheline
d71f606: slub: fix ksize() build error
b3d4188: slub: fix kmemcheck calls to match ksize() hints
3ff84a7: Revert "slab: Fix missing DEBUG_SLAB last user"
6331046: mm: Remove support for kmem_cache_name()
The crash is below.
